Abstract: An edible aqueous inkjet ink and a tablet. The edible aqueous inkjet ink contains a relatively large amount of volatile alcohol, which has improved or even excellent transfer durability and reduces ink ejection failure. The tablet includes a portion printed with the edible aqueous inkjet ink. The edible aqueous inkjet ink according to the present embodiment includes food coloring, ethanol, and a surfactant which has a hydrophilic-lipophilic balance value (HLB) in a range of 16 or more and 20 or less. The food coloring may preferably be sodium copper chlorophyllin. The surfactant may preferably be a sucrose fatty acid ester.
